Method, apparatus, system and non-transitory computer readable medium for code protection

A non-transitory computer-readable medium storing computer readable instructions, which when executed by at least one processor, causes the at least one processor to execute a code protection method, wherein the code protection method comprises:

• storing a package file that includes a plurality of files of an application on a storage device, the package file including, a first protection module file for restoring a transformed protection target method or function associated with the application;
• restoring the transformed protection target method or function using the first protection module file in response to execution of the application, the restoring including generating execution code based on the transformed protection target method or function and the package file;
• and
• executing the generated execution code using the first protection module file,
• the method further comprising:
• cloning the protection target method or function;
• adding the cloned protection target method or function to the first protection module file;
• adding discovery code to the generated execution code, the discovery code including instructions for discovering the cloned protection target method or function in the first protection module file;
• the executing of the generated execution code using the first protection module file comprises executing the generated execution code by discovering the cloned protection target method or function from the first protection module file using the discovery code with respect to the selected protection target method or function;
• encrypting at least one instruction of the cloned protection target method or function of the first protection module file using a first encryption key or a first encryption algorithm;
• and
• adding decryption code for decrypting the encrypted instruction to the cloned protection target method or function of the first protection module file.

A code protection method of an electronic device, the method comprising:

• storing, using at least one processor of the electronic device, a package file that includes a plurality of files of an application on a storage device of the electronic device, the package file including, a first protection module file for restoring a transformed protection target method or function associated with the application;
• restoring, using the at least one processor, the transformed protection target method or function using the first protection module file in response to execution of the application, the restoring including generating execution code based on the transformed protection target method or function and the package file;
• and
• executing, using the at least one processor, the generated execution code,
• the method further comprising:
• cloning, using the at least one processor, the protection target method or function;
• adding, using the at least one processor, the cloned protection target method or function to the first protection module file;
• adding, using the at least one processor, discovery code to the generated execution code, the discovery code including instructions for discovering the cloned protection target method or function in the first protection module file;
• the executing of the generated execution code using the first protection module file comprises executing the generated execution code by discovering the cloned protection target method or function from the first protection module file using the discovery code with respect to the selected protection target method or function;
